' MIXING Ann BEATIN'G MACHINE.

Application filed June 16, 1920. Serial No. 339,340.

To all wZwmmitmay concern: I

Be it known that we, HENRY TRUST, a citizen of the United States, and resident of Park Ridge, in the county of Bergen and State ot New Jersey,-and FRANK M. Asrr LEY, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented "oertain new and useful Improvements in Mixing and Beating Machines, of which the followingis a specification; I

Our invention relates to mixing and beating machines and the object of our invention is to provide a machine adapted to mix and beat food stuffs such as the whites of eggs, cream, and such other elements as require to be formed in light flakes or emulsified. We have discovered that air or other suitable gas will assist in preparing such foods if properly introduced into the said foods under pressure while the food is being agitated or stirred by a beater.

Referring to the drawings which form a part of this specification:

Figure 1 is an elevational view of a machine, shown partly in section, whlch embodies our invention.

Figure 2 is a plan view taken on hne 22 of Figure 1.-

Figure 3 is an elevational view shown partly in section, illustrating a good way to make the container and gas conduit construction.

A indicates a sheet metal receptacle of the usual character employed for use with 1nixmg and beating machines, and B indicates a beater which is rotated as it revolves in the receptacle in the usual manner well known in this art. G indicates a tube coiled about the lower end of the receptacle A and closed at one end by a removable plug C The tube is soldered 0r otherwise suitably fastened to the outer surface of the receptacle, and small conduits C etc., are made through the wall of the receptacle and tube through which the gas flows from a reservoir D under pressure controlled by the reducing valve E. F indicates a pump which compresses the gas in said reservoir. In Figure 3 is shown a metal band G having a number of conduits Ci'-G'G' which are connected by a vertical passage Gr indicated in dotted lines. This band is secured to the receptacle by rings of solder H-H.

' the receptacle. A'pipe I is connected to number of jets, and by reason of the ingredients being whipped by the beater while the gas is flowing into the mass, the ingredients absorb a portion of the gas or enclose it in the form of small bubbles, and the surplus gas escapes from the open top of the receptacle, By this new method and construction, the ingredientsmay be properly prepared in a shorter time than by the old methods and machines and form a more perfect product.

Having. thus described our invention we claim as new and desire to secure by Letters Patent:

1. In a mixing and beating machine including a beater, a receptacle in the form of a bowl having a smooth interior, a band mounted on the outer surface of the bowl, a-conduit formed between the band and the adjacent bowl portion to encircle the latter in air tight relation to the exterior, openings leading from the conduit through the wall of the bowl to form outlets, and an inlet for the conduit formed inthe band directly communicating with all of said outlet openings and adapted to be connected to a fluid pressure source, said outlets being arranged in vertical. and in horizontal spaced relation for directing the fluid from the conduit into the path movement of the said beater.

2. In a mixing and beating machine. including a beater, a receptacle in the form' of a bowl having a smooth interior and a closed bottom, a band firmly secured on the outer surface of the bowl, a conduit formed between the band and the adjacent bowl portion to. encircle the latter in air tight relation to the exterior, openingsleading from the conduit through-the wall of the bowl toform outlets, and an inlet for the conduit formed in the band directlycommunicating with all outlets and adapted to be connected to a fluid source, said conduit being helical shaped for arranging the said outlets in to be deflected and brokenupinto a greater vertical and horizontal spaced relation to direct the fluid from the conduit into the path of movement of the said beater.

3. In a mixing and beating machine including a beater, a receptacle in the form of a bowl having a smooth interior, a band. mounted on the outer surface of the bowl, a conduit formed between the band and the adjacent bowl portion to encircle the latter in air tight relation to the exterior, open.- ings leading from the conduit through the wall of the bowl to form outlets, said opening being positioned at the the bottom side of conduit to drain same and an inlet for the conduit formed in the band directly communicating with all of saidfoutlet openings and adapted to be connected to a fluid pressure source, said outlets directing the fluid from the conduit into the path of movement of the said beater.

4c. In a mixing and beating machine includilig a heater, a receptacle in the form ot' a bowl having a smooth interior and a closed bottom a band firmly secured on the outer surface of the bowl, a conduit formed between the band and the adjacent bowl portion to helically encircle the latter in air tight relation to the exterior, openings leading from the conduit through the wall of the bowl to form outlets, said opening being positioned at the bottom side of conduit to drain same, and an inlet for the conduit formed in the band directly communicating with all outlets and adapted to be connected to a fluid source, said outlets arranged to direct the fluid from the conduit into the path'of movement of the said beater.

Si ned at New York city in the county of l ew York and State of New York this 10th "day of June, A. D. 1920.

HENRY TRUST. FRANK M, ASHLEY.
